Answer: Third option.

Step-by-step explanation:

We need to remember these properties:

log_b(a)^n=nlog_b(a)\\\\log_b(b)=1\\\\\frac{1}{a}=a^{-1}

Then, given the following expression:

log_2(\frac{1}{64} )

You need to:

- Descompose 64 into its prime factors:

64=2*2*2*2*2*2=2^6

- Substitute:

log_2(\frac{1}{2^6} )

- Apply the properties shown above:

log_2(2)^{-6}=-6log_2(2)=-6(1)=-6

Round 19.98 to the nearest whole number
DiKsa [7]
19.98 rounded to the nearest whole number is 20. 
In the number 19, 9 round the 1 to a 2 and the 9 becomes a 0 because of the 9 behind the decimal. 
OR
You could think of a percent being 100. 98 is only 2 numbers away from 100 and thus you can round 19 up to 20.

Hope this helps! (:
